Bug Description


ironic node-list | grep True | xargs -n1 ironic node-update replace /maintenance=False

BBEEPP, nope.

If we could have the node uuid last, or allow an option to specify it - e.g.
ironic node-update replace /maintenance=False -n
then we could do this :)

Oh ewwww. Cool, but ewww.

I'd like deva's perspective on whether this is really invalid or not - reopening for that.

I'm also often annoyed by not being able to use xargs, and instead having to write out a complete for loop...

for N in $(ironic node-list | grep True | awk '{print $2}'); do ironic node-update $N replace /maintenance=False; done

It's not as neat... but this isn't really a problem.

I think adding an optional "-n UUID" argument, to those CLI operations that accept a node uuid, is reasonable and does not break compatibility with the current CLI.
